Abstract

In a multicast VPN [RFC6513] deployed with BGP-based procedures [RFC6514], when receivers in VPN sites join and leave a given multicast group or channel through multicast membership control protocols (Internet Group Management Protocol (IGMP) [RFC3376] and Multicast Listener Discovery (MLD) [RFC3810]), multicast routing protocols accordingly adjust multicast routing states and P-multicast tree states to forward or prune multicast traffic to these receivers. Similar challenges arise in the context of the multicast specification for Virtual Private LAN Service (VPLS) [RFC7117].

                       Multicast VPN State Damping

Abstract

   This document describes procedures to damp Multicast VPN (MVPN)    routing state changes and control the effect of the churn due to the    multicast dynamicity in customer sites.  The procedures described in    this document are applicable to BGP-based multicast VPN and help    avoid uncontrolled control-plane load increase in the core routing    infrastructure.  The new procedures proposed were inspired by BGP    unicast route damping principles that have been adapted to multicast.
